Municipal sludge is the main potential secondary polluting source during sewage treatment since it contains a large number of organic pollutants and hazardous components such as pathogens, heavy metals and carcinogenic chemicals.

Veolia builds and operates many urban sludge treatment plants throughout the world. In doing so, it has developed a unique expertise in landfill gas fermentation, soil remediation applications, waste incineration for electricity generation (Waste-to-Energy), cement recycling and other recycling technologies – sludge composting treatment and co-combustion of sludge and municipal solid waste are the most mature of Veolia’s widely-used technologies.

The experience and expertise which Veolia has garnered over the years is continuously reducing and preventing the emission of greenhouse gases, especially as related to sludge treatment, where exchanges, internal communication and the sharing of resources and talent will better enable the development of sludge treatment opportunities/projects with municipalities in China.
